Abstract
The sulphate is reduced by tin(II) chloride in hydriodic acid to hydrogen sulphide which is swept by nitrogen into a buffered solution of bis(2,9-dimethyl-1,10-phenanthroline) copper(II) ion. The resulting copper(I) complex is measured spectrophotometrically. With sample volumes between 10 and 1000 μl, the limit of detection is 0.5 μg of sulphate. Formation of the stable complex is immediate and the reduction system can be used repeatedly. The method is applicable to fresh, estuarine and marine waters.
